Red imported fire ants

​​Current situation

Red imported fire ant (RIFA) (Solenopsis invicta) is one of the worst invasive species to reach Australia's shores, and continues to be the target of a national cost-shared eradication programs.


Fire ants were first detected in February 2001 at the Port of Brisbane and in the south western suburbs of Brisbane, South-east Queensland. Spread from the initial Brisbane detection led to infest​ations around the greater Brisbane area including Ipswich, Logan and Redlands. Isolated infestations have also been found in the Scenic Rim, Gold Coast and Lockyer Valley areas. Subsequent incursions were detected at Yarwun (2006 and 2013), Brisbane Airport (September 2015) and the Port of Brisbane (May 2016).

Fire ants have been declared eradicated from Yarwun, and are expected to be eradicated from Brisbane Airport and Port of Brisbane in 2018.

The South-east Queensland and Brisbane Airport incursions are subject to nationally cost-shared eradication programs, while the eradication program for Port of Brisbane is funded by the Commonwealth.​

Fire ants were detected at Port Botany, Sydney in November 2014 and have been subject to a successful nationally cost-shared eradication response.

The Port Botany incursion has been declared eradicated.

Further information on the fire ant eradication response at Port Botany can be found on the NSW Department of Primary Industries website.

Reporting detections

Fire ants represent a serious threat to our health, environment and economy. Members of the community and industry play an important role by reporting suspected detections. Early reporting is a vital part of preventing fire ants from establishing and spreading. Fire ants are a notifiable pest in most Australian states and territories, which means there is a legal obligation to report suspected detections. This obligation applies to everyone, including individuals and organisations.

Anyone who suspects that they have seen fire ants or any other type of exotic invasive ants should report sightings to the Exotic Plant Pest Hotline on 1800 084 881. This number will put you in contact with your local department of primary industries or agriculture.
